Bradley Cooper Introduces First Trailer for 'A Star Is Born' at CinemaCon

The remake of the classic 1937 film marks Cooper's feature directorial debut and Lady Gaga's first film as an actress.

Meet Lady Gaga, the movie star.

Bradley Cooper on Tuesday introduced the first yet-to-be released trailer for his film A Star Is Born at CinemaCon in Las Vegas during Warner Bros.' star-studded presentation before theater owners. The pic is Gaga's first feature film as an actress.

A Star Is Born is slated to hit theaters Oct. 5, a prime corridor for awards fare. Insiders say the release date was set after executives saw a locked cut of the movie, which Cooper directed and also stars in. MGM is Warner Bros.' partner on the film.

Warner Bros. Pictures Group chairman Toby Emmerich said Tuesday the movie is an "extraordinary directorial debut."

The trailer features plenty of singing by Gaga, along with a duet featuring Cooper, who said at CinemaCon that Gaga insisted on them both singing live. "She said what she can't stand in movies is when it's playback and they are lip-syncing," he said.

The upcoming pic continues Hollywood's love affair with the 1937 film of the same name (which starred Janet Gaynor and Fredric March) about a movie star who helps an aspiring young actress find fame, even as age and alcoholism send his own career into a downward spiral. It was subsequently remade in 1954 by director George Cukor, with Judy Garland and James Mason starring, and again in 1976, with Barbra Streisand and Kris Kristofferson headlining.

Cooper's take has a country music feel, as did the 1976 version. Sam Elliott and Andrew Dice Clay co-star in the pic.

"It's a big swing, this movie," said Cooper, who also had to learn how to sing to portray his country musician character. "I totally get that. You can't control what moves you. You can't contrive or manufacture something that moves you. This project was always around. It always stayed with me."
